The invention relates to the desulfurizing method of high-sulphur iron ore power, in particular to the iron ore power recycled by using sulfurous iron ore, pyrites and floatation gangue. When the content of sulphur of the iron ore concentrate, which is mostly magnetite, reaches over 15 percent, by adopting the principle of asynchronous size classification, the iron ore concentrate can reach ...
May 01, 2007· The use of column flotation was considered for the "reverse flotation" of iron ore, where the gangue (quartz) was recovered in the froth product. This use of the froth for carrying the gangue mineral rather than carrying the valuable concentrate significantly changes the operational requirements of the column. The objective of this work was to determine which of several column …
